When it first came out, I was intrigued. The science made sense to me, and at my age, I could feel myself start to slow down. After about three days, I felt a difference: more energy, less fog, didn't want to nap in the afternoon, etc.
I then stopped for a few days, and before long I was back to my previous self. Repeated the process a few times. Every time I stopped, it felt like someone took out my batteries.
That was years ago. A while back, I decided to double the dosage, and things got even better. This is the only supplement I take. I've given jars to my friends, mostly good, but didn't work for everyone.
Bottom Line: Yes, I would recommend this to a friend
